Abstract
Der zylindrische Schalldämpfer (50) umfasst eine Luftaustrittsöffnung (54) zum Anschliessen an den Anströmkanal des Verdichters eines Abgasturboladers sowie einen zur Luftaustrittsöffnung führenden und dabei mindestens eine Umlenkung von der radialen Richtung in die axial Richtung vollziehenden Strömungskanal. Der Verdichtergehäusezusatz (40) weist einen ringförmigen Hohlraum (43) und eine in den Hohlraum mündende Zuleitung (44) für ein gasförmiges Medium auf. Im Bereich einer stirnseitigen Gehäusewand (51) des Schalldämpfers sind Einblasöffnungen (55) vorgesehen, welche axial gerichtet sind und den ringförmigen Hohlraum (43) mit dem Strömungskanal des Schalldämpfers verbinden. Durch die Einblasung des gasförmigen Mediums in die zu verdichtende Luft vor der Umlenkung der Strömung beim Aust, erfolgt bei ebendieser Umlenkung eine Vermischung des gasförmigen Mediums mit der Luft sowie eine Eliminierung der durch die Einblasung entstehenden Verwirbelungen in der Ansaugströmung.The cylindrical muffler (50) comprises an air outlet opening (54) for connection to the flow channel of the compressor of an exhaust gas turbocharger and a flow channel leading to the air outlet opening and at least one deflection from the radial direction to the axial direction. The compressor housing additive (40) has an annular cavity (43) and a feed line (44) for a gaseous medium opening into the cavity. In the area of an end wall (51) of the muffler there are blow-in openings (55) which are axially directed and connect the annular cavity (43) to the flow channel of the muffler. By injecting the gaseous medium into the air to be compressed prior to diverting the flow at the exit, the gaseous medium is mixed with the air as well as this deflection, and the turbulence in the intake flow caused by the injector is eliminated.
Description
Technisches GebietTechnical area
Die Erfindung bezieht sich auf das Gebiet der Abgasturbolader für aufgeladene Brennkraftmaschinen.The invention relates to the field of exhaust gas turbochargers for supercharged internal combustion engines.
Sie betrifft einen Verdichtergehäusezusatz zur Anordnung zwischen dem Schalldämpfer und dem Verdichtergehäuse eines Abgasturboladers, mit welchem ein gasförmiges Medium in den Anströmkanal des Verdichters eines Abgasturboladers eingeblasen werden kann. Die Erfindung betrifft weiter eine Schalldämpfervorrichtung mit einem solchen Verdichtergehäusezusatz, sowie einen Abgasturbolader mit einer Schalldämpfervorrichtung mit einem solchen Verdichtergehäusezusatz.It relates to a compressor housing addition to the arrangement between the muffler and the compressor housing of an exhaust gas turbocharger, with which a gaseous medium can be injected into the inflow passage of the compressor of an exhaust gas turbocharger. The invention further relates to a muffler device with such a compressor housing additive, as well as an exhaust gas turbocharger with a muffler device with such a compressor housing additive.
Stand der TechnikState of the art
Für die Leistungssteigerung einer Brennkraftmaschine (Verbrennungsmotor) werden heutzutage standardmässig Abgasturbolader mit einem der Brennkammer der Brennkraftmaschine Luft für den Verbrennungsvorgang zuführenden Verdichter und einer Abgasturbine im Abgastrakt der Brennkraftmaschine eingesetzt. Mit der Aufladung der Brennkraftmaschine wird die Luft- und Kraftstoffmenge in den Brennkammern (Zylindern) erhöht und daraus ein merklicher Leistungsanstieg für die Brennkraftmaschine gewonnen. Der dafür verwendete Abgasturbolader setzt sich standardmässig aus einem Rotor, bestehend aus einem Verdichterrad und einem Turbinenrad sowie der Wellenlagerung, den strömungsführenden Gehäuseteilen (Verdichtergehäuse, Turbinengehäuse) und dem Lagergehäuse zusammen.For the increase in performance of an internal combustion engine (internal combustion engine) exhaust gas turbochargers are nowadays used by default with one of the combustion chamber of the internal combustion engine air for the combustion process supplying compressor and an exhaust gas turbine in the exhaust tract of the internal combustion engine. With the charging of the internal combustion engine, the amount of air and fuel in the combustion chambers (cylinders) is increased and obtained from this a significant increase in power for the internal combustion engine. The exhaust gas turbocharger used for this purpose is composed of a rotor consisting of a compressor wheel and a turbine wheel as well as the shaft bearing, the flow-guiding housing parts (compressor housing, turbine housing) and the bearing housing.
Je nach Motortyp oder Anwendung kann es vorkommen, dass der zu verdichtenden Luft zusätzlich ein gasförmiges Medium, beispielsweise bereits verdichtete Luft, sogenannte Verdichter-Bypass-Luft oder Luft-Brennstoff-Gemische oder gasförmige Brennstoffe oder beispielsweise Gase aus der Entlüftung des Kurbelgehäuses von Gasmotoren, zugeführt werden.Depending on the engine type or application, it may happen that the air to be compressed in addition a gaseous medium, for example already compressed air, so-called compressor bypass air or air-fuel mixtures or gaseous fuels or gases from the venting of the crankcase of gas engines, be supplied.
Damit der Verdichterbetrieb nicht durch lokal variierende Strömungsgeschwindigkeiten oder Turbulenzen, welche ungewollte Anregungen der Laufschaufeln des Verdichterrades verursachen können oder durch thermische Schichtungen in der Strömung gestört wird, hat eine solche Zuführung eines gasförmigen Mediums über eine ringförmige Einblasöffnung und möglichst in einem grossen Abstand zum Verdichterradeintritt zu erfolgen. Damit die einzudüsende Luft- oder Gasmenge gleichförmig über den Umfang des Anströmkanals auf den Verdichter verteilt wird, ist vorteilhafterweise hinter der ringförmigen Einblasöffnung eine Ringkammer mit einem ringförmigen Hohlraum zum Sammeln und Verteilen der Luft oder des Gases angeordnet.
Ein Schalldämpfer für einen Abgasturbolader ist etwa aus der
Soll bei einem direkt am Abgasturbolader aufgesetzten Schalldämpfer zusätzlich vor dem Verdichter ein gasförmiges Medium eingeblasen werden, stehen sich die Anforderungen aus Schwingungsverhalten der Einheit Abgasturbolader und Schalldämpfer und Strömungseigenschaft des Verdichters gegensätzlich entgegen.If a gaseous medium is additionally injected in front of the compressor in a muffler placed directly on the exhaust gas turbocharger, the requirements of the vibration behavior of the exhaust gas turbocharger and muffler unit and of the flow property of the compressor are opposite.
Kurze Darstellung der ErfindungBrief description of the invention
Die Aufgabe der Erfindung besteht folglich darin, einen Verdichtergehäusezusatz zu schaffen, der zwischen dem Schalldämpfer und dem Verdichtergehäuse eines Abgasturboladers angeordnet werden kann, und welcher trotz kompakter Bauweise die Zuführung eines zusätzlichen, gasförmigen Mediums in den Strömungskanal vor dem Verdichter ermöglicht, ohne dass dabei die Strömungseigenschaften des Verdichters beeinträchtigt werden.The object of the invention is therefore to provide a compressor housing additive, which can be arranged between the muffler and the compressor housing of an exhaust gas turbocharger, and which despite compact design, the supply of an additional, gaseous medium in the flow channel before the compressor allows without the Flow characteristics of the compressor are affected.
Erfindungsgemäss wird dies dadurch erreicht, dass der zwischen dem im Ansaugbereich des Verdichters angeordneten Schalldämpfer und dem Verdichtergehäuse vorgesehene Gehäusezusatz derart ausgebildet ist, dass er die Einblasung in den Strömungskanal vor der Umlenkung der Strömung im Ansaugbereich aus der radialen in die axiale Richtung ermöglicht. Die Einblasung erfolgt dabei im Bereich der verdichterseitigen Stirnseite des zylindrischen Schalldämpfers, wobei in die stirnseitige Gehäusewand des Schalldämpfers Einblasöffnungen eingelassen sind, welche einen ringförmigen Hohlraum im Innern des Gehäusezusatzes mit dem Strömungskanal im Innern des Schalldämpfers verbinden. According to the invention this is achieved in that between the arranged in the intake of the compressor muffler and the compressor housing housing addition is designed such that it allows the injection into the flow channel before the deflection of the flow in the intake from the radial to the axial direction. The injection takes place in the region of the compressor-side end face of the cylindrical muffler, wherein in the end-side housing wall of the muffler injection openings are inserted, which connect an annular cavity in the interior of the housing additive with the flow channel in the interior of the muffler.
Durch die Einblasung des gasförmigen Mediums in die zu verdichtende Luft vor der Umlenkung der Strömung beim Austreten aus der zentralen Öffnung des Schalldämpfers erfolgt bei ebendieser Umlenkung eine Vermischung des gasförmigen Mediums mit der Luft sowie eine Eliminierung der durch die Einblasung entstehenden Verwirbelungen in der Ansaugströmung.By injecting the gaseous medium in the air to be compressed before the deflection of the flow as it exits the central opening of the muffler takes place at this same deflection, a mixing of the gaseous medium with the air and an elimination of the resulting turbulence in the intake flow through the injection.
Der Gehäusezusatz umfasst zusätzlich zum koaxial zur Welle des Abgasturboladers angeordneten, ringförmigen Hohlraum mindestens eine Zuleitung zum Zuführen eines gasförmigen Mediums in den Hohlraum. Der Hohlraum weist auf der dem Schalldämpfer zugewandten Seite eine Ableitungsöffnung auf, durch welche das gasförmige Medium auf die Einblasöffnungen in der Gehäusewand des Schalldämpfers und in den Strömungskanal im Schalldämpfer geführt werden kann.The housing addition comprises in addition to the coaxial with the shaft of the exhaust gas turbocharger arranged, annular cavity at least one supply line for supplying a gaseous medium into the cavity. The cavity has on the muffler side facing a discharge opening through which the gaseous medium can be performed on the injection openings in the housing wall of the muffler and in the flow channel in the muffler.
Optional ist im Hohlraum eine Blende angeordnet, welche den Hohlraum in zwei Teilhohlräume unterteilt, welche über eine Durchströmöffnung miteinander verbunden sind. Diese Unterteilung sorgt für eine verbesserte Verteilung des gasförmigen Mediums entlang des Umfangs des Hohlraums, so dass das gasförmige Medium gleichmässig verteilt über die Einblasöffnungen der Strömung im Schalldämpfer zugeführt werden kann. Die Blende ist optional scheibenförmig und derart bemessen, dass sie sich in axialer Richtung durch die Ableitungsöffnung in den Hohlraum einsetzen lässt.Optionally, a diaphragm is arranged in the cavity, which subdivides the cavity into two partial cavities which are connected to one another via a flow-through opening. This subdivision provides for an improved distribution of the gaseous medium along the circumference of the cavity, so that the gaseous medium can be fed evenly distributed over the injection openings of the flow in the muffler. The diaphragm is optionally disc-shaped and dimensioned such that it can be inserted in the axial direction through the discharge opening into the cavity.
Weitere Vorteile ergeben sich aus den abhängigen Ansprüchen.Further advantages emerge from the dependent claims.
